I think I would get a JD 740 loader. 260 265 loader bucket/implement attachment system is a little outdated. 740 uses the 600/700 attachment system still has support. Latest is the Global system.
740 is avaliable in with or without MSL (mechanical self leveling), and designed for MFWD tractors. Mounts are available for your model. Check with dealer what models of tractors share mounts that fit yours.
Look for repairs due to abuse, welds, patches, twisted arms, bent cutting edge on the bucket. Worn pins.
Check condition of hoses, cylinder rods (bent, rust, nicks, heavy scratches), cylinder leaks.
If you plan on removing time to time make sure it has park stands, and quick disconnects on the hoses.
